The composition comprises a mixture of: i) poly(L-, D-lactide) homopolymer and, optionally, poly(&#x3b5;-caprolactone) homopolymer, and ii) poly(L-lactide) and poly(&#x3b5;-caprolactone) diblock copolymer, where said copolymer has a molar mass of the L-lactide block of 20,000 g/mol to 200,000 g/mol and a molar mass of the &#x3b5;-caprolactone block of 10,000 g/mol to 100,000 g/mol, with the molar ratio between the L-lactide block and the &#x3b5;-caprolactone block of 2:1. The invention also refers to the nanostructured material obtained from this composition that is characterised by a nanostructure of two mutually self-assembled phases, one phase being formed by a polymeric matrix of poly(L-, D-lactide) units and the other phase by poly(&#x3b5;-caprolactone) units self-assembled with the matrix and also its use for the manufacture of a plastic article in the form of a transparent film or thin sheet.

Polymer nanocomposite having: a) a polylactic polymer; and b) a modified phyllosilicate composition having a modifying agent which includes hexadecyl trimethyl ammonium cations which are intercalated between the layers of the phyllosilicate; and preparation process of such a polymer nanocomposite. The polymer nanocomposite is particularly useful for packaging, particularly food and drink packaging.
